Japan’s three largest banks — Mitsubishi UFJ Bank, Sumitomo Mitsui Banking Corporation (SMBC), and Mizuho Bank — are moving toward jointly issuing a yen-pegged stablecoin by the end of the 2026 fiscal year (March 31, 2027). The initiative, reported by Nikkei, comes after months of joint testing under the supervision of the Financial Services Agency (FSA) that began in November 2025. A dedicated council formed by the banks will now focus on operational design, real-world use cases, and commercialization strategy, while a formal collaboration agreement is expected to be signed shortly.
The move builds on Japan’s 2022 legislation that classifies stablecoins as digital money and restricts issuance to licensed banks and trusts. The FSA actively encouraged the three banks to collaborate rather than launch competing stablecoins, aiming to create a single, regulated digital yen instrument. Details remain scarce regarding retail vs. institutional access, cross-border compatibility, custodial arrangements, and reserve infrastructure. However, the combined deposit base and payment dominance of the three megabanks, coupled with FSA oversight, could make the stablecoin a significant piece of Japan’s financial infrastructure.
Globally, the project highlights a trend of traditional financial institutions entering the stablecoin space. If successful, it could shift some settlement activity away from offshore dollar-pegged stablecoins like USDT and USDC toward regulated, bank-issued alternatives, potentially serving as a model for other major economies.
